Abstract
The group of polysaccharides known as B-glucans (cellulose, 1.6 and 1.3-glucans) together with hemicelluloses (xilans, arabinogalactans and L-arabinans) are generally responsible for causing technical problems such as turbidity and viscosity in processing of grapes and wines. A solution to this problem is the addition of exogenous enzymes that degrade these polysaccharides such as pectino…
